Agreed, Once - back in the day - when I was living in RES, I heard a story about the top floor (of a concrete 11 story building) turning their large bathroom into a large large hot tub.  After that a structural engineer did some calculations and found that they were still a few tons below a structuaral failure.  Good old res hey...
